T 0 (M 70/1/0710 may concern:

Be it known that we, Trroims S. HAMIL- 'roN and Jo on A. Moons, citizens of the United States, residing at Louisville, in the county of J efferson and State of Kentucky, have invented certain new and useful Improvements in Box-Stitching Machines, of which the following is a specification.

This invention relates to a device for stitching or stapling together the end flaps of fiber board containers, and the invention resides particularly in a form of anvil or abutment suitable for use with commercial forms of stitching heads.

In the drawings z- Figure 1 is a side elevation of the complete device, many of the mechanical details of the stitching mechanism being omitted or only diagrammatically represented as they are not involved in the present invention;

Fig. 2 is an end elevation of the same, showing a container in place and partially stitched by the stitcher head; and

Fig. 3 is a view similar to Fig. 2 but showing the anvil swung to one side at the completion of the stitching operation.

In the drawings 1 represents the supporting pedestal of the machine and 5 the overhanging arm thereof, while 6 represents diagrammatically the stitching mechanism of the head which may be of any preferred or usual form. In the machine chosen for illustration, power is applied by means of a wheel 7 and the staples or other fasteners are cut and formed from a continuous strip or wire fed from a magazine spool 8.

The parts so far referred to are illustrated merely to represent any suitable commercial form of stitching mechanism.

In conjunction with this we make use of an anvil against which the staples or other fasteners are clenched by the stitcher head, the anvil being so arranged as properly to support the receptacle and to be readily manipulated so as to release the same upon the completion of the stitching operation. The anvil structure comprises a base 9 which is securely fastened to the floor by bolts 10. The base 9 carries an upstanding yoke or frame 11 to the upper end of which is fulcrumed by means of the pin 12 an upstanding arm 13, whose upper end terminates in the anvil proper 1 1 which is preferably of metal and is properly formed on its top sur- Specification of Letters Patent.

face to cooperate with the stitching mechanism in clenching the fasteners.

The member 13 is limited in its latcral swinging motion by two adjustable stop screws 15 which are locked by check nuts 16 in lugs 17 These lugs 17 are formed di rectly on the upstanding yoke or frame 11. When the member 13 is swung so as to con tact with the right hand stop, as viewed in Fig. 2, the anvil 14 is directly beneath the stitcher head in proper cooperative relation therewith. hen the member 13 is in con tact with the left hand stop then the upper end of the member 13 and the anvil 14 stand to the right clear of the stitcher head to permit the removal of a stitched box or the positioning of a box to be stitched. In order to retain the member 13 in its vertical or operative position we make use of a plate spring 18 having a bow or hump 19 on its upper face which serves as an impositive latch to hold the member 13 in its vertical position. The spring 18 may be depressed with the foot in order to release the member 13 when desired.

In order to operate upon materials of dif ferent thickness the anvil lt is made adjustable toward and from the stitcher head. This is done by threading the shank of the anvil 21 into the end of the arm 13 and providing a lock or check nut 22.

In the various figures we have illustrated containers 20 in position for stitching, the sides of said containers being partially broken away in Figs. 1 and 2 to show the anvil 14-. Containers of this type are usually formed with four overlapping end flaps and by the use of our improved anvil it is possible to stitch all four of these flaps together at once in a quick and inexpensive manner, thus producing a much stronger container than is possible by prior methods.

Having thus described our invention, what we claim is 1. In a device for stitching the end flaps of boxes, the combination of a stitcher head; a base provided with stops and a fulcrum pin; an upstanding member provided with an anvil and fulcrumed on said pin to swing between said stops into and out of cooperative relation with said stitcher head; an impositive spring latching mechanism adapted to hold said member in such cooperative relation; and means operable by the foot of an operative for releasing said latching mechanism.

2. In a device for stitching the end flaps of boxes, the combination of a stitcher head; a base provided with stops and a fulcrum pin; an upstanding arm fulcruined on said pin to swing between said stops; an anvil mounted on said arm to swing therewith into and out of cooperative relation. with 19 said stitchei' head and adjustable on said arln toward and from said stitchei' head; a

latching device for holdingsaid anvil in such cooperative relation to said stitcher head; and means operable by the foot of an operative for releasing said latching device.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
